ELEcTaIc SEALING-WAX MACHINE.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed September 12, 1911. Serial No. 648,885.

.. To all whom it may concern:

Baltimore, in the State of Maryland,

Be it known that I, ARTHUR LOGKARD, a citizen" of the United States, residin at ave invented new and useful Improvements in Electric SealingVVax Machines, of which the following is a specification.

The general objects of theinvention are to accelerate the operation of sea-ling packages with ordinary sealing Wax; to prevent injury, by burning, to the hands of the operator; to insure the consumption of the entire stick of wax, whereby, to overcome the loss occasioned by discarding the butts or small ends remaining after the major portion of the stick has been consumed; and to elimi- I mate the danger of fire either to thepackage caused by applying blazing wax thereto or to.surrounding objects by discarding burn ing matches used for heating the Wax.

Other objects will appear and be better understood from the following description taken in connection with the accompanying drawings, in which,

Figure 1 is a side elevation of the device the standard or upright thereof being contracted by removing asection as indicated by the broken lines. Fig. 2 is a plan with a portion-of the top wall of the casing re moved. Fig. 3 is a detail longitudinal sec- U011. of the head. Fig. 4 is a horizontal cross section of the head. Fig. 5 is a vertical cross section of the same approximately on the line 5 5 of Fig. 3.

5 indicates the base of any suitable size and contour found convenient for supporting the device against toppling under the weight of a package and while in use.

6 indicates an upright or support to which is adjustably connected the package holding support or platform 7 The element 7 may be-of any suitable construction such as that shown wherein 8 indicates a disk connected in any preferred manner such as by screws 9, to an arm 10 which lies a slccvc 11 to loosely receive the upright (3. A set screw 12 being employed for securing the sleeve to the upright 6.

a'indicates the head which is supported by the upright 6 and which includes anouter casing 18 in which is confined a hollow walled heating chamber 14, an electric heatingcoil 15 arrangcd in the hollow wallof the chamber 14 and a wax container 16, slidingly fitted in the chamber 14 and adapted to deliver its contents or a portion thereof to a package (not shown) situate on the package-holding platform 7. The heating chamber 14 is arranged obliquely with re-- spect to the upright 6 and its hollow wall is lined with a suitable non-conductor such as asbestos 17. The coil 15' is connected to the electric conducting wires 18, which together with the flexible cord 20 are connected to the switch 19, the latter serving to control the passage of current throughthe coil 15. The cord 20 has a plug (not shown) at its free end to connect with a lamp socket or the like.

The container 16 has a'closed end 21 and opening in the end Wall 22 of the casing 13 and has a top or closure 23 detachably connected thereto and locked in any preferred manner, such as-by a set screw 24. The bearing surfaces of the heating chamber. and container are machined or otherwise treated so as to insure a true fit and bypreference the bore of the heating chamber and the con: tainer are rectangular 'in cross section. 25 indicatesan ,outlet or discharge opening in the lower wall of the container 16 and when the container-is in normal position as shown by full lines in Fig. 3, this opening blanked by the heating chamber 14 and thus, the contents of the container prevented from escaping through the opening- 25. This, however, is merely illustrative of one means for cutting off the flow of wax' through the opening 25 and it will beseen that when the parts are positioned as shown by dotted lines in Fig. 3, r. a. when the closed matically or otherwise to uncover the opening as the container is projected and to seal tion may be employed for effecting the foregoing result, such as by arranging a post 26 in the slot 27 'n the upper wall 28 of the casing and employing a link 29 to connect a post 30 on and then connecting the opposite ends of'a' retractile spring 31 with the link and the .casin 13;

Re errin'g now to Fig. 3, the parts are held in the' position shown by means of the spring 31 one endof the slot 27 also serving as' a stop and holding the container a'xains'ttoo far inward movement 1nto the heating chamber 14. In this connection it will be observed that the closed end 21 of the container is flush, or substantially so with one end of the heating chamber 1%. Assuming now that the current is turned'on and pass? through the coil 15 and the wax 32 in'.

ing the containerreduced to a viscous state by the heat. When the container is projected by moving the post 26 to the opposite end of the slot 27' as shown b dotted lines in Fig. 3,.the wax will flow 1: rough the opening 25. In this connection it will be observed that the said opposite end of the slot 27 acts as astop for the post 26, whereby, to limit outward movementof the con tainer. The narts'are held in these positions. until a required amount of wax is'deposited onto the package'after which the post is re leased whereupon the spring 31 will return the parts to the position shown-by full lines in Fig. 3'. This done, th soft waxon the package is pressed with; e usual seal. In the drawings I have she asealarranged between the sides of ,the casing 13 andin front of the end j wall 21'}of the container. The seal it adapted to be turned'into contact with the wax after the same has been deposited. Any preferred construction .may be employed for efiecting the foregoing resuch as by arranging a shaft 33 so as to.

suit,

7 turn in the side'wallsof'the casing 13, and

connecting to this shaft a seat body 34: and

a or nk handle 35 for turning the shaft. Wit this construction, the parts will be positi'oned as shown in Fig. 1 sothat after the wax has been applied the crank handle may be turned to the left in Fig. 1 so as to move theseal to the position'shown in Fig. 3 and unto the situate thereunder.

By virtueghf the adjustability of the packthe container with the post 26 isin one position age holding platform 7, the latter may be positioned to various distances from the head a to conform to the thickness of the package.

The heating chamber is secured in the easing in any preferred manner such as by pins 36 passing through the sides of the casing 13 and into fillets 37 in the side walls of the chamber.

' By virtue of incliningfthe wax container it will be seen that the wax will more readily flow therefrom and at the same time this construction will insure that substantially all the wax may be drawn off before a new piece is inserted into the chamber.

Although I have shown and described one embodiment of the invention it is to be understood that I am not to be limited to the specific arrangement and construction of parts since various changes will be made,

within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention. Whathl claim as new is:

1. In a device of the class described, the f combination with a support for the object to be sealed, a heating chamber, a movable wax container adapted for feeding the heated wax onto the article, and slidingly fitted in the heating" chamber, and a seal connected toithe heating chamber andpositioned above the support.

2. In a device of the class described, the combination with an adjustable support for the object to be sealed, a'heating. chamber, and a movable wax container adapted for feeding the heated wax onto the article and arranged in the heating chamber.

3. In a sealing apparatus, the combination with a support for the article to he sealed, and a heating chamber; of a wax container adapted for feeding the heated wax onto the article and slidingly fitted in the heating chamber and inclined frtnn the horizontal for the purpose described.

' 4. In a sealing apparatus,-the combination with a support forthe article to be sealed; of a heating chamber located above the support, a wax container slidingly fitted in the heating chamber and adapted for feeding the heatedwaxonto the article, and means for operating the container.

5. In a sealing apparatus, the combination of a ollow walled chamber, an electric heating coil arranged in the said hollow wall, and a wax container; slidingly fitted in the heating chamber-and having a dis charge opening adapted when. the container 7 to be sealed by the wall of the heating chamber. '6. Ina sealing apparatus, the combination of an adjustable'support for the article to be sealed, a hollow walled heating chamber locatedabove the support, an electric heatchamber when -the said container is; in one posi tion.

In testimony whereof I afiix my signature 1n presence of two WltIlQSSGS.
